I 2 Claims. (ar as-271.1)

My, invention relates, to improvements in steam pans, so called, such as are used in thawing out frozen ground and vegetation, eradicating certain kinds of weeds, and for similar purposes.

The invention is designed with the primary object in view of equipping such pans with inexpensive, simply constructed means for transporting the same over the ground to difierent locations or sets of plants, and elevating or lowering the pan as occasion may require.

Other and subordinate objects are also comprehen-ded by my invention, all of which, together with the precise nature of my improvements, will be readily understood when the succeeding description and claims are read with reference to 1 the drawings accompanying and forming part of this specification.

In the drawings:

Figure 1 is a view in plan of my invention in its preferred embodiment,

Figure 2 is a view in rear end elevation,

Figure 3 is a view in side elevation and showing the position of the parts when the pan is elevated,

Figure 4 is a similar view with the pan lowered,

Figure 5 is a fragmentary view in transverse section taken on the line 5-5 of Figure 3 and drawn to an enlarged scale,

Figure 6 is a fragmentary view in perspective of one rear corner of the pan and parts carried thereby.

Referring to the drawings by numerals, according to my invention, the usual elongated, rectanular steam pan I with vertically straight front and rear ends 2, 3, similar sides 5, a flat top 5, and a steam inlet nipple 4 is equipped with a pair of ground wheels 6 and a wheel carriage I.

The wheel carriage I is of yoke-like form and comprises a fiat bar 8 coextensive in length with the width ofthe pan I and extending across the top 5 of said pan I in the transversecenter of said pan, and a pair of bar-like uprights 9 rising from the sides 4 of said pan, respectively, well above the top 5 with lower ends I fitted flat against said sides 4 and the ends of the bar 8 suitably secured thereto, as by welding, not shown. The top of the pan I and the sides 4 thereof may be secured to the bar 8 and the lower ends III of the uprights 9 in any desired manner. A pair of crossed diagonal strut rods II suitably connected at their ends to the uprights 9 above the pan I brace said uprights and incidentally the sides 4 of the pan I against lateral flexing. A pair of front strut rods I2 extend downwardly and forwardly from the upper ends of the up- I to swing rights!) to upright; anchorbars I3 bolted, as at I4, to the front end 2 of the pan I adjacent the sides of said pan, said rods I2 bracing the pan l forwardly of the uprights 9 against sagging. A pair of rear strut rods I5 and anchor bars I6 similar to rods I2 and bars I3 similarly brace the pan I against sagging in the rear of the uprights 9.

The ground wheels 5 are mounted on a pair of crank-type axles having relatively long ends I! journaled in the uprights 9 in overlying relation to the pan I and also in a pair of bearing brackets IB suitably fixed on said bar 8, the crank ends I9 of the axles trailing the uprights 9 so that the pan I is over-balanced forwardly of the ground wheels 6. Pins 20 in said ends I! at the inner sides of the uprights 8 and washers 2I on said ends between the crank ends I9 and said uprights prevent endwise play of said axles. Suitable washers 22 on the crank ends I9 back the ground wheels 6 which may be secured on said crank ends in any conventional manner.

A pair of hand levers 23 are pivoted, as at 24, to the uprights 9 adjacent the upper ends of said uprights to extend rearwardly therefrom and for vertical swinging movement. A pair of operating bars 25 are pivoted-at upper ends thereof, as at 26, to said levers 23 in the rear of the pivots 24 with lower ends pivoted, as at 21, tothe crank ends IQ of said axles, as best shown in Figures 3 and 5. The levers 23 and bars 25 are soarranged that by swinging said levers downwardly, the carriage I and pan I may be elevatedabout the axis of the ground wheels 6 to lift the pan I oif the ground. Conversely, by permitting the levers 23 upwardly into substantially horizontal position, the carriage 1 and pan I may be lowered 1 about the axis of said ground wheels to seat said pan on the ground. A pair of hook-shaped keepers 28 are provided on the sides 4 of the pan I adjacent the rear corners of said pan and beneath which the levers 23 may be swung to lock said levers in downwardly swung position and the pan I elevated. The keepers 28 are bolted, as at 29, to the sides 4 of said pan.

A suitable draft tongue 30 extends forwardly from the bar 8 in the longitudinal center of the pan I' and through a holding bracket 3I bolted to the top 5, as at 32.

The described invention is designed to be connected, by the tongue 30, to anysuitable draft vehicle, not shown, and it is comprehended by my invention that suitable provision may be made for introducing steam from the draft vehicle into the pan I at will.

The foregoing will, it is believed, suflice to impart a clear understanding of my invention, since the operation thereof has been explained in connection with the description of parts.

Manifestly, the invention, as described, is susceptible of modification without departing from the inventive concept, and right is herein reserved to such modifications as fall within the scope of the appended claims.

WhatI claimisr v v 1. In apparatus" of the class described, a pan of rectangular form having a, closed top, and adapted for receiving steam, a pair of ground wheels at opposite sides of said pan, means to.

elevate and lower the pan about the axis of said wheels, and a draft tongue for; '-the;,pan,- said means comprising a pair of crank-type axles for said wheels, a pair of uprights'risinffrom 6pmsite sides of said pan and in which said axles arejournaled in overlying relation to said pan, .a pair of vertically sw'iriga'ble levers pivoted up said up rights at the upper ends thereof, and a pair of bars pivotally connected to said levers and to the cranks of said axles.

2. In apparatus of the class described, a pan of rectangular form having a closed top, and adapted for receiving steam, a pair of ground wheels at opposite sides of said pan, means to elevate and lower the pan about the axis of said wheels, and a draft tongue for the pan, said means comprisinga pair of crank-typeaxles for said wheels, a pair "or u rights rising from opposite sides of said pan and in which said axles are joumaled fin overlying relation t said pan, 9. pair of vertically swingable levers pivoted to said uprights at th'etop thereof, a pair of bars pivotally connected tosaid-levers-and to the crank of said axles, and a pair of keepers on said pan with which said levers may be'engaged by lateral flexing oi the levers, said keepers preventing upward swinging of the levers.
